Part Number: AM62A7
Sensor: ox05B1s
Tool/software: AM62A processor SDK v11.01.07.05
I was using gstreamer to capture image:
Some setup I used.
"v4l2src device=/dev/dms io-mode=dmabuf-import ! "
"video/x-bayer,width=1944,height=1946,framerate=30/1,format=bggi10 ! "
"tiovxmemalloc ! "
"tee name=dms_isp_tee "
And it works.
Now I am trying to use TIOVX pipeline to capture images from sensor OX05B1s.
I am not sure how to create node to do this job. I have tried to create tivxCaptureNode, but I didn't see any captured data.
here is how i setup code:
"
tivx_capture_params_t capture_params;
tivx_capture_params_init(&capture_params);
// Configure for camera (single instance)
capture_params.numInst = 1U;
capture_params.numCh = 1U;
capture_params.instId[0] = 0U; // CSI-RX instance 0 for DMS
capture_params.instCfg[0].enableCsiv2p0Support = static_cast<uint32_t>(false);
capture_params.instCfg[0].numDataLanes = 4U;
capture_params.instCfg[0].laneBandSpeed = TIVX_CAPTURE_LANE_BAND_SPEED_720_TO_800_MBPS;
capture_params.chVcNum[0] = 0U;
capture_params.chInstMap[0] = 0U;
auto _capture_config = vxCreateUserDataObject(_context,"tivx_capture_params_t",sizeof(tivx_capture_params_t),&capture_params);
if (vxGetStatus(reinterpret_cast<vx_reference>(_capture_config)) != VX_SUCCESS)
{
std::cerr << "[TiovxCameraApp] Failed to create capture config\n";
return -1;
}
_capture_image_array = vxCreateObjectArray(context,reinterpret_cast<vx_reference>(raw_image),
NUM_CAPTURE_BUFFERS);
if (vxGetStatus(reinterpret_cast<vx_reference>(_capture_image_array)) != VX_SUCCESS)
{
std::cerr << "[TiovxCameraApp] Failed to create capture image array\n";
return -1;
}
_capture_node = tivxCaptureNode(_graph, _capture_config, _capture_image_array);
"
My expctation is this part of code will capture image from sensor.

Could you please provide some guidance or documentation on how tivxCaptureNode works? I would like to understand the required setup and the parameters that need to be prepared before using it.
Any hints, examples, or references would be greatly appreciated.
